Spills and splatters are common if you use a microwave oven. If you’ve let them build up you can have a hard mess to clean. Here’s an easy way to do this: in a microwave-safe bowl combine the juice of one lemon and 1/2 cup of water, throw in the rinds too, and heat your microwave for 3 minutes. The D-limonene in the lemon peel, the citric acid in the lemon juice, and the water’s steam combine to loosen any gunk or grime so it wipes right off.
